Two aircraft maintenance technicians (amts) were informed that an md-88 aircraft they had just performed an 'M' procedure for an MEL deferral of the right engine fuel/oil heat valve; had developed uncontrollable high fuel and oil temperatures on climbout; requiring an inflight engine shutdown. Valve had been physically positioned to the 'closed' position; but not safety wired and vibrated to the 'open' position after engine start-up.

Narrative:
While working with contract maintenance in ZZZ on a MEL deferral of the right engine fuel heat valve. All MEL procedures were complied with except for wiring the position indicator into place to secure the valve. On climb out; crew had high fuel and oil temperature. Crew was unable to control oil temperature and shut the right engine down. Aircraft off landed in ZZZ1. Landing was uneventful.
